Variation in TPS each time I look
#21
No offense Mike, but I don't have a car sitting in front of me to look at to know which is top or bottom. I gave you a screenshot of the wiring diagram that shows a picture of the connector (with positions) and even gave you the colors.
That said, I think we are 99% sure that you are getting 5v to the TPS.
What is interesting though is the .5v that you are getting on the top wire.
According to that, the wire you are getting .5v from SHOULD be a ground. Instead of metering voltage, check resistance to ground. I am guessing this has something to do with your problem.

I will double check in the morning when I have better light but those are different colors than I have. It looks like mine are B/LG = 5v, B/R = Ground, G/B = .5v
I will verify everything tomorrow to be sure. But I wired the VRef to the B/LG, Ground to B/R and TP Signal to G/B
Thank you for your help (sorry, I was out to dinner earlier)

You sure brain? That's not the way it looks in the wiring diagram.
B/R = Black with Red stripe = sensor ground
G/B = Green with Black stripe = signal
LG/R = Light-Green with Red stripe = vref
I am confused though because black/light green doesn't show up as a throttle related wire. Mind you, my wiring diagrams aren't for a 2003 but I have one for both a 2000 and a 2001 and they both agree with the colors and signals I posted here.
EDIT:
Rather than argue about it I just went outside and metered my own.
My wires meter out as:
B/R = Black with Red stripe = sensor ground (ground)
G/B = Green with Black stripe = signal (happens to be just under 5v at the moment for some reason)
LG/R = Light-Green with Red stripe = vref (5v)
B/R = Black with Red stripe = sensor ground
G/B = Green with Black stripe = signal
LG/R = Light-Green with Red stripe = vref

I wasn't looking to be honest. All 90-97s use b/lg as a sensor ground wire and that went out the window in 99. so when I saw the reference to that I was like well there's an issue.
Looks like I was still correct about the wiring issue, lol.
